class_docstr: A column object, with only the methods and properties required by the
  interchange protocol defined.
  A column can contain one or more chunks. Each chunk can contain up to three
  buffers - a data buffer, a mask buffer (depending on null representation),
  and an offsets buffer (if variable-size binary; e.g., variable-length
  strings).
  Note: this Column object can only be produced by ``__dataframe__``, so
        doesn't need its own version or ``__column__`` protocol.
docstr: See `self.dtype` for details.
